Castro Framing Shop Since 1985: Underglass, No Appointment

Underglass Custom Framing sits at 2239 Market Street in San Francisco's Castro, and its website says plainly that no appointment is needed. Walk in Monday to Friday between 11 am and 6 pm, or on Saturday and Sunday between 11 am and 5 pm, and someone at the counter will start the conversation about your piece. The shop has been framing in the neighborhood since 1985, which is why the city has named it an official Legacy Business. If you typed framing shop into your phone because a print, a jersey or a diploma has been leaning against a wall for months, this is a shop where you can simply bring the thing in and talk it through.

Underglass describes itself as San Francisco's frame shop since 1985, and its own pages say the roots in the Castro run deep enough that the city recognizes it as a Legacy Business. That label is given to long-running neighborhood institutions, and you feel it in how the shop talks about its role. The website calls it a community hub, with fundraisers for LGBTQIA+ causes, rescue animals shown in the shop and art shows for up-and-coming local artists. Every frame sold helps pay for that programming, so a purchase here is partly a contribution to the street itself.

The two founders are named on the Our Story page. Matthias is originally from Germany, trained in photography at the San Francisco Art Institute and has been part of the city's art scene since 1994. Eric grew up in Michigan, came to framing through fashion design and says his taste mixes Motown and pop culture with classic and modern looks. That pairing explains the range of work the shop shows online, from a vintage etching in a modern room to a 1977 Metropolitan Museum poster and a mosaic dog portrait. The owners also describe themselves as an LGBTQ-owned business.

The services list is wide, and it is worth reading before you go so you know which category your piece falls into. Photographs can be printed in house and framed in one visit. Fine art, from paintings to drawings and digital art, gets museum-quality conservation framing. Documents such as newspaper clippings, graduation certificates and ketubahs are treated, in the shop's words, as family heirlooms. Concert posters, limited edition prints and vintage illustrations fall under graphic art, and the shop will help you pick a frame that reflects your taste rather than the poster's age.

Two specialties set the shop apart from a generic framer. Textiles and jerseys are hand-sewn onto archival materials before a custom frame is built around them, which suits flags, scarves and sports shirts that would be damaged by tape or glue. Dimensional art, meaning objects, is mounted in custom shadow boxes or acrylic boxes so the piece is reversible, safely attached and well preserved. Canvas work is covered too, from professional stretching of oil or acrylic paintings to in-house canvas printing.

Size is rarely a reason to stay home. The shop says that as long as a piece fits through its door, it can frame it, and for oversized work you can email or call to talk through options, including delivery. Prints made through the online ordering system can be as wide as three feet and as tall as six feet, and you pick them up at the Market Street storefront.

The process starts with you, according to the website: stop in to explore design options in person, send an email, or request a quote through the site. Because no appointment is needed, the simplest plan is to bring the piece itself, flat and protected, so the framers can hold corner samples against it. The shop mentions a happiness guarantee on its banner, and customer reviews on the site describe a patient, collaborative process in which staff offer several creative options and keep an eye on the budget you give them.

One practical rule is timing. A custom job is not a same-day product, and one reviewer who left a photograph for a month before pickup describes the wait as part of the experience. If you need something fast, ask about the readymades, a curated collection of ready-made frames in common sizes with UV-filtering glass, which the shop recommends for last-minute gifts or quick home updates. Gift certificates are sold in the store, so you can also buy a framing credit for a friend who has a stack of unframed posters.

The shop also advertises 20 percent off your first order, and it offers the same discount on your next frame or print when you sign up for its newsletter, with restrictions applying. Ask at the counter how the offer applies to your project before you commit to a design, because the discount depends on the order.

The honest decision most people face is whether their piece needs a custom job at all. A standard photo in a common size can often go into a readymade, which is the quick, inexpensive route and still comes with UV-filtering glass. Anything irreplaceable, unusual in size or sentimental deserves the custom treatment: a signed jersey, a family document, a print with margins that must not be trimmed. One reviewer on the site had an unusually sized photograph, and the shop cut a custom mat that fit a standard frame, which is a smart middle path worth asking about.

Skip the temptation to pick the most ornate moulding for a modest print. The shop's own description of its work leans on pairing frames with the art, minimal for some pieces and classic ornate for others, so bring a photo of the wall where the frame will hang and let the framers steer the width of the mat and the colour of the wood.

Market Street through the Castro is easy to turn into a short afternoon. The Castro Theatre marquee, one of the neighborhood's best-known landmarks, is a few blocks along the street, and Harvey Milk Plaza at the Muni station entrance is the natural place to pause. Both are free to look at from the sidewalk. Dropping off a piece first and walking afterward works well, because the framers can start measuring while you wander.

Because the shop opens at 11 am on every day it is open, a late-morning visit leaves the whole afternoon free. Weekday afternoons tend to be quieter than weekends, which matters if you want unhurried time to compare corner samples. On Saturday and Sunday the shop closes at 5 pm, an hour earlier than on weekdays, so arrive with at least an hour to spare.

Address: 2239 Market Street, San Francisco, CA 94114. Phone: (415) 252-9844. Email: info@underglassframing.com. Hours on the shop's website: Monday to Friday 11 am to 6 pm, Saturday and Sunday 11 am to 5 pm. No appointment is needed.

Bring the artwork flat, in a folder or between boards, and photograph the wall where it will hang. For textiles and jerseys, bring the item clean and unfolded if you can. For oversized pieces, email or call before you carry it over so the team can plan the handling. Prints ordered online are collected at the storefront. Ask the Karpo APP for more local shops and nearby plans in the Castro whenever you want a second stop for the afternoon.
